[Bug 276170] LLVM bug prevents from enabling PGO optimization for Python 3.11+

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276170

--- Comment #14 from Dimitry Andric <dim@FreeBSD.org> ---
Never mind, I can reproduce here on a 14.0-RELEASE-p3 arm64 VM, with the system
clang which is 16.0.6.

However, I also tried clang 17 from ports and that works fine with all the
files. Since I am currently working on MFCing llvm 17 to stable/14 and
stable/13, I'm unsure if it is worth the time to spend on figuring out which
upstream commit fixed this.

That said, for 14.0 release it might be fixed in an errata notice, but it is
quite a lot of work, and this problem only occurs in a very specific use case
(which can be worked around easily), and will be made moot anyway after 17 is
MFCd...
